MANIFOLDING ATTACHMENT FOR TYPEWRITERS.

Application led October 3, 1923. Serial No. 886,289.

To alli/110m it may concern Be it known that l. MAloLM L. COSSI'IT, a citizen of the United States. residing at Oakland,. in the county of Alameda and State of California, have invented certain new and useful Improvements in Manifolding Attachments for Typewriters, of which the following is a specification. Mv invention relates to that class of manifolding attachments for typewriters in Which there is associated with the main paper guide apron on the platen carriage of the machine adapted to direct a record sheet to the line of type impact. a second apron memher or a plurality thereof in spaced relation to the main apron and adapted to direct additional record sheets to said line. said second apron memher or members being in the form of containers to house manitolding members, such as carhon sheets. and to present an exposed section of said sheets between the record sheets in the line ot' type impact. This form ot' attachment is disclosed in niv previous Patent. No. 1,433,183 dated Oct. 24. 1922; and my present invention is an improvement in this type, the improvel'nent` consisting essentially in providlng for the independent movement of the containers to earr)r primaril)r the exposed section of the manifolding sheets into and out of functional position in the line of type impact. and secondarily to vary said exposed section with relation to the said line, While said section is in functional position.

Referring to Fig. 1, the numeral 1 indicates the end pieces of the platen-carriage,

in which is rotatably mounted the shaft .2 of the platen 2.n 3 is a portion of the main inking ribbon of the machine. extending between and carried by the ends 1 of the laten carriage parallel with the platen an lying below the line of type rmpact, said rod being the member upon which the spring controlled paper feed-rolls 4 are pivotally mounted. 5. is the rocking rod adapted to move said rolls to and from the laten. 4 The rods 4 and 5 together with the bracket 6 and its foot roller 7, Figs. 2 and shown merely to indicate convenient parts found in a well known type of machine, and serving as a mount for certain operative mechanisms to' be carried by the platen carriage, and comprised in m attachment, as will be hereinafter describe S is affixed rail carried on the frame of the machine, a portion of which is indicated at 8 and upon this rail the foot roller 7 travels hack and forth with the platen carriage, Figs. 2, 10 and 13. For the purposes of my invention this rail 8 indicates any part oi' the machine frame ixed with relation to the platen carriage movement and serves as a means for carrying other mechanisms of my attachment to be presently described. 9, Figs. 6 and 13, is the main aper guide apron carried by the ends 1 o theplaten carriage'. This apron is in general. like the ordinary apron of typewriters. It extends from an elevated line back of and properly spaced from the platen, downwardly towards and under the platen for the usual portion'of the lower arc thereof as seen in ig. 13. It is to be noted, however, that, for purpose hereinafter described, the main apron 9 is made in sections hinged together at 9', Fig. 13, whereby the lower section may be turned back when necessary. Secured to the inner face of the apron 9 as seen in Fi 6 are plates 10 one near each end. Carrled by and between the plates 10 are the U-shaped sheaths 11, one or more in number, three being here shown. These sheaths are dis osed with their closed bights Vuppermost an their open ends downward as shown in Fig. 8; and with respect to each other and to the main apron they are relatively widely spaced above and thence con- 10, are herein 4 is ai rodit and the main apron verge downwardly towards Vthe platen as seen by the dotted lines in Fig. 13. The sheaths 11 thus form initial supplementary paper guide a rons for a plurality of record sheets intro uced between them. Said sheaths are removably mounted on the plates 10, being fitted between guide ianes and held by spring latch pins 10, igs. 1 and 14. 12 are containers for the manifolding members. The containers are best made of springy sheet metal folded centrally to a double thickness as seen in Fig. 8, the folded end fitting snugly but slidab y in the sheaths 11. Emerging from the open end of the sheaths the containers with their double walls pressing relatively closely, Fig. 8, pass down under the platen, between 9 as 1n Fig. 13, and extend beyond said main apron and up in front of the platen as seen in Figs. 1, 6, 8 and 13, thus forming in conjunction with their sheaths guide aprons for other record sheets. Each container at each end of its front edge is formed with arms 13 under which the paper feed-rolls 4 play as seen in Fig. 1; and between these arms the front edge of the container is depressed as seen at 12 in Fig. 1 below the line of type impact. The end arms 13 connect each container with corresponding end members or sectors 14, the hubs 14 of which are rotatably and linearly slidably mounted upon the journal bearing 2" of the platen shaft 2', as seen in Fig. Ll, and are provided with hand levers 15 for operating them, Figs. 1, 5, 6 and 13. The manifolding members indicated by ,16, Figs. 1, 11 and 12 are best in the form of carbon papel' each being initially a web of any desired length, the intention being' to. use a web adapted to be drawn upon for use during a relatively long period of time. The carbon paper is stored in proper form, say, for example, fan-folded, as indicated 1n the containers 12, which portions are slidabl housed in the sheaths 11. The end of eac strip of carbon paper is drawn out between the relatively close pressed walls of the container, see Fig. 12, until a ribbon llke section is exposed in the line of type impact as seen in Fig. 1 above the depressed front edge l2 of said container.

The operation of the attachment as far as descri ed is as follows:

'lhe containers 12 being loaded with their supply of carbon paper '16 as in Fig. 12 and fitted in their sheaths 11, and about the platen, all said containers are by means of the hand levers 15 partially withdrawn to a position to carry their exposed section of carbon paper out of use, that is to say, the containers slide upwardl in their sheaths, their front edges with tieir protecting exosed carbon paper sections being thereby owered below the line of type impact. In

Fig. 12 in the folded upper portion of,

llt',

this position the typewriter may be used to make only the single record in the usual manner, no du licate being.;r desired.

If now one tuplicate he wanted a second record sheet is introduced upon the upper surface of the sheath ll nearest the main apron 9, the first record sheet. being introduced upon the main apron, and both sheets are fed forward by the platen to the line of type impact. 'l'heiv arc however separated by the intervening container 12 and then this container, by lhe operation of the appropriate hand lever 15 is mort-d forward to carry its exposed section of carbon paper into registry with the line of type impact, said section lying between the two iecord sheets. 'lf a .second carbon is wanted the above dcscrilied adjustment of the nextcontainer isinade in like manner, and so too with the third container-when a third carbon is desired. 'lhe relation of the several record sheets indicated in dotted lines by 50, and the carbon sheets 16 are 'clearly seen in F ig. 11. lVhen that ribbon-like section of the carbon paper 16 exposed to the. im-

pact of the type, is exhausted, it is drawn forward from the open end ofthe container. and torn off, and by this operation a fresh ribbon-like section of carbon paper is exposed for use; and this may be continued until the supply of carbon papel' stored in the container is used up.

To reload the containers, theyare removed from their sheaths, an operation permitted by the hinged section of the main apron 9. Fresh carbon paper supplies are then placed in the containers by merely spreading them open sufficiently and then all the parts are assembled once more. The containers 11).. in order to render them sufficiently flexible may be slotted as shown in Fig. l0 at l. In the practical operation of manifolding devices wherein the manifolding impression member is presented in the form of a ribbon-like section of a sheet or strip, successive sections of which are. drawn out lor use, it is necessary, in order to give the section a maximum life of usefulness, that it be presented in such manner as 'to receive the impact of the type over its entire surface. This is accomplished by repeated limited adjustments of the section with relation to the line of type impact, in some cases the adjustment being an oscillation cross- Wise of said line, in other cases, -lengthwise thereof and in still others both' orosswise 'and lengthwise, the latter being the most complete, in that it takes care both of the Width of the section and of the intervals lengthwise between the points of impact. This is shown in Figs. 18 and 19. Furthermore, in some cases, this adjustment or oscillation is dependent upon and effected at the time of the line'spacing movement of the platen, andA in other cases it is effected bon papers both crosswise of the line/of. type impact aud lengthwise thereof. and al'- though in the broadest aspect of my invention these means may be dependent either upon the lino-spacing movement of thev platen or upon the reciprocative travel of the platen carriage, I prefer a construction utilizing the earriagetravel. This will now be explained. Securedto and extending be tween the corresponding end sectors 14 of cach container 12 is a crank-bar 17, best seen in Fig. 5.

Secured to some portion of the fixed frame of the machine, here shown as the rail 8, is a standard 18, Figs. 2 and 10, in thc head of `which is journaleda ratchet 19 carrying an eccentrically located stud Q0 against which the edges of the crank bars 17 are adapted to bear when the `'containers have been initially moved, as heretofore described, in order to place their ribbon-like sections of carbon paper in functional position in the line of type impact. Springs 21, Fig. 13, applied to the hand levers 15V serve to hold said bars 17 to said stud; while yieldable latches 21 as in Fig. 13 enacting with pins 17 on the ends of hars 17 counteract .aid springs to hold the bars away from the eccentric pin 20, when the containers are drawn back out of use. Upon the bracket (i carried by the rod'4 of the platen carriage is secured a springr pawl 2.2 adapted to engage the ratchet 19 in one direction and to slip it in the other direction, Figs. 0 9 and 10. It; will now .be seen that when, duringthe travel of the platen carriage, the spring pawl 22 engages the ratchet 19, it will turn said ratchet. one tooth and the eccentrically located stud 20 of said ratchet bearing against the crank bars 17 will correspondingly.slightly move .the containers 12 to carry their ribbon-like sections of carbon paper crosswise of the line o f type impact; and', on account of the eccentric closed path of the stud 20, and the fact thatthe crank bars 1T are held against it, this crosswise adjustment will be au ultimately rcciprocative, orback and forth adjustment of the exposed sections of the manifolding members across the line of type impact, thereby utilizing the entire width of the said sections. It will be noted that as the crank bars 17 contact with the stud on one side only and only when the containers are in functional position, the main adjustment of said containers to carry them into and out of functional osition is not interfered with, as the crank ars may be withdrawn backwardly away from the stud altogether and lll.)

Vthe platen-shaft bearings 2.

held back by the latches 21'. It will also be noted that any 4one or more of the crank bars may be moved down to coact with said stud, according to the number of carbon copies desired.

To provide for the lengthwise oscillation of the manifolding member containers, there is the following mechanism.

lt will be seen by reference to Fig. 4 that the hubs 14 of the end sectors 14 of the containers12 are so mounted upon the journal bearings 2 of the platen shaft 2' as to be capable not only of rotary movement, but of a linear movement as well, sufficient play on said bearings being provided. It follows that if said sectors be moved linearly, the containers 12 will adjust their exposed sections of carbon paper lengthwise of the line of type impact. It will also be seen. that as the crank bar 17 of the` outermost container isthe first to be moved into functional position, a. longitudinal movement imparted to v"said bar will not only adjust its own container, but will also adjust the other containers, due to the grouping of the hubs 14 of the sectors 14 of said containers upon Therefore, whether one or more carbo'n sections are being used, the longitudinal movement of the outermost crank-bar will effect the required linear adjustment.

Referring now to .F igs. 13, 15, 16 and 17, there is `secured upon the bracket 6 carried by the rod 4 of the platen carriage a bracket 23, upon which is rotatably mounted an annular ratchet 24 which at a given point in the travel of the platen carriage is adapted 'to contact with and to be rotated by a fixed sto member 25 on the frame of the machine. Lying withinthe'annular ratchet asin Figs. 15 and 16 and independently rotatable is a disk 26, the periphery of which has a JSeries of cams 27 so related to the inner 4terier'cam disk 26 is circle of the ratchet, that in conjunction with intervening rolling members 28, the

'rotation of the ratchet in one direction will clutch the cam disk 26 and turn it, while the rotation of the ratchet in they other direction will slip the cam disk 'and allow it to remain stationary. Therefore although the ratchet `24 by its contact with the fixedV stop 25 first on one side and then on the other due to the reciprocative travel of the platen carriage, is merely oscillated, the inrotated step by step inla closed circular'path in one direction on y. i

Eccentrically mounted in the cam disk 26 is a stud 29, over which is slotted one end of a lever 30 pivoted on the bracket 23 at 31, and having its other end slotted upon a" stud 32 carried by the outermost crank-bar 17 of the first container. 12, Figs. 15 and 13.

'When'the ratchet 24 reaches Vand contacts with one side of the fixed stop 25 it will be disk, by means of its eccentric stud 29, will 4 swing the lever 30; and said lever, by reason of its engagement with the stud 32, will linearl shift the crank bar 17 which, as heretofbre described, will eifectl the lengthwise shifting of the container and theexposed section of the carbon paper. This o eration takes place on the return of the p aten carriage; but on the forward stroke theratchet 24 though enga ed by the fixed stop 25 and thereby turne back will slip the cam disk 26, and not turn it; whence 1t follows that the container is not affected. On the next return travel of the laten carria e the container will again shi ted and ultimately, due to the closed path on the eccentric cam-disk stud 29 the carbon paper section will be linearly shifted step by step in one direction and then step by step back again. It will thus be seen that by this lengthwise adjustmentA in con- `junction with the crosswise adjustment, the manifolding section will present substantially its entire surface during its useful life.
